i since move the port facing inside and the subs up (was short on wires)
and it doesnt sound as great...there is far less rattling from the hatch but
weaker bass

110 square inches or so; or 2 6" areo ports.

areo ports are more efficient at moving air than rectangular ports.
They can use less area and (therefore) less depth to achieve the
same Mach rating (whistle/port noise factor) and tuning.

Oh. Ok.

What about corner loading the port(s)?

You could put the areo ports, if you went that way; low, rear firing and equi-centered (not right next to each other in the middle). You would also want to give the port 6-8" of distance between the box and the rear hatch of the SUV. Basically, your loading off the back wall, then up along the roof line primarily, and secondarily into the corners and back along the sides.

In a previous setup I gained 1.5db subs up port back over subs and port back. In my current setup I gained 0.5db sub up ports to the driver's side over sub up ports back. This doesn't work in all circumstances though. Subs up and ports back is a good safe route. I agree that two 6" ports are perfect for that sub.

No problem. :)

6 cubes is not a huge box, so you need to look into whether
it is better to build the box with a gap between the side walls
for the wave to come back forward, or if you want to force most
of it up by building the box exactly wide enough to fit in the back.

I'm actually not sure which is better.

One thing that's also very important that hasn't been taken into consideration is the type of SUV. My team has 4 suv's on it (2 Explorers, a Blazer, and Jeep Cherokee) and not every one of them wanted the same firing position.

Sweet.

I'm thinkin I'mma just build a sub up port back box and turn it until I get the best result.

Thanks!

Oh and how big should I build my box?
It is gettin pretty smelly in 6 cubes, thinkin about shrinkin it to 5 to handle the power better; but won't that hurt my debeez?
